BUILDING FORM.

ToaZZ 'whom t may concern.' p

Be it known that I, Lnwrs IV. Timon, a citizen` of the United States,rresiding at Miami, inthe county of `Dade and 'State of Florida', have invented certain new and useful VImprovementsina Building Form; and I do hereby fdeclarethe following to be a full, clear, andiexact description 'of the invention, such' as will enable others skilled in the art Vto which it appertains to make and use the same. f s

The object of the invention is to provide a simple, inexpensive and efficient means adapted to serve as a filling unit forrbuilding forms as a substitutefor the wooden fillers ordinarily employed between the joists and girde-rs in concrete and'similar work in connectionV with ybuilding operations, and more especially to provide a unit which can be used repeatedly and for an indefinite length of time and is readily adaptable to the varying spacings to be foundbetween the joists and other timbers in building and which for general use must be'capable of adjustment in width to correspond with such Vspacings which are ordinarily modified in building operations to suit the purposes for which the structures are designed; and with this object in view the invention consists in a construction and combination vof parts of which a preferred embodiment is shown inthe drawing, where- 1n:-

Figure 1 is an elevation of a filler unit embodying the invention arranged the operative position with relation to joists or like building timbers, the latter being shown in cross section, and the outside form of a Vwall being shown fragmentarily.

Figure 2 is a detail view in perspective of the units detached.

Figure 3 is a sectional view of the device in lapplied position, showing fragmentarily a wall. Y

The `device is constructed preferably Vof sheet metal such as steelin the form of a plate of suiiicient gage to afford the necessary stability, and it preferably is con-l structed of sectional form to provide a piurality of members 10 and 11 adapted for arrangement in parallelism and in contact and for relative sliding movement or ad- Vjustment to vary the width of the filler,

measured from theouter edge of one member to the opposite or remote edgeV of the other member, to correspond with the intervals between'the joists `or other timbers in connection with which they are to be used.

In the construction illustrated the members are provided with perpendicularly disposed supporting arms 12 and 13, preferably consisting of members of angular brackets which `are respectively attached to the members of the filler and are provided with perforations 14 through which nails 15 maybe driven to attach the brackets, and hence the members of the filler to the flooring 15 to prevent displacement thereof during the positioning of the' concrete or cement, .it

being preferable to drivethe'se nails, as

shown in the drawing, only a part of the way and then to bend them over as indii cated so that they mayl readily be withdrawn when the unit is to be displaced at the cornpletion of the operation.

One of the members o f the unit is provided with a flange 16 formed by turning over or foldingY back one edge of the same to constitute an interlocking engagement with the'corresponding edge of the other member, so as to constitutey a simple means of maintaining them in their proper relative positions so far as their upper andlower edges are concerned while providing for a relative sliding movement thereof to vary the distance between their side edges to correspond with the interval between the adjacent surfaces of the joists or timbers indicated for example at 17 and between which the deviceis positioned in lieu of the fillers ordinarily employed in concrete conv struction work.

The application of the invention is best shown in Figure 3 where outside and inside building forms 1S and 19 are shown and a concrete wall 20 is shown between the Vforms Vwith the ends of the joists 17 extending into the wall. The filler, comprising my invention, is illustrated between a pair of adjacent joists and rests upon the upper outer edge of the inside form 19 closing the spce between a pair of joists adjacent their en s.

In applying the filler the member 10 thereof may be positioned and secured by driving a nail in a perforation of the supporting arm, after which the other member may be dropped into place to interlock at its flanged edge with the corresponding edge ofthe first named member and after positioning the second members with its side edge in proper relation With the surface o" the adjacent joist or timber it may be secnred by nails driven through a perforation of the supporting arm thereof to secure the two members in coopera-tive relation, and it will be obvious that said operation of positioning the liller may be accomplished Without loss ol time and very much more expeditiously than cany the ordinary Wooder1-fillers be located in a similar relation to the joists or timbers of a building, with the additional advantage that after the concrete has been poured and allowed to set, the fillers herein described may be readily removed and used again Whereas the ordinary Wooden fillers are destroyed or renderedV inetlfective in the removal thereof, under ordinary circumstances, so as to involve a considerable Waste of timber in addition to the loss of time incident to arranging the same inl proper position for use.

Having thus described the invention, What I cla-im is l. A filler unit for building forms having a sectional plate consisting of 1elative ly movable members arranged in parallelism and provided With means for attachment to the building timbers', one ot the members being provided' with a'marginal flange having a sliding engagement with the adjacent edge ofV the other member.V

2. A filling unit for buildingforms comprising a plate consisting of relatively adjustable members adapted for arrangement between adjacentjoists, each of said members being provided With supporting meansV attaching arms each provided `with perforations adapted to receive fastening means. In testimony whereof I aiiix my Vsignature in presence of tW'o Witnesses. 'Y l Y LEWIS W. TILTON. IWitnesses F. L. TERRY, A.W. SEYMoUn.
